This invention relates to an improved Y o J molded toilet seat or coverand is particularly concerned with thenovel constructionofthe I hingearms molded integral with the main 'ingof. the seat orcover;

body portion of the seat or cover. :1 1

, One of the principal objects of the inven tionisto provide," in anovel construction of the character referred to, an especiallypractical' and efiective'rneans for reinforcing the hinge armsconsisting jof hollow. perforated which themolded material will, readilyflow and form abondi' A; further object is to provide the inserts in theform of stamped sheet metalparts' viding afbearing liningwithin anopening molded in the" outer end o f the hinge arrrrifor the receptionof thehinge pin in the mountesAside from thezadvantage as to savln'g fcost' resulting from any. limproved construction and the advantages ofneatnessinfappearance and practically .indestructibility',

quent polishing to maintain a proper cleanly is to be mentioned the factthat thev present construction presents no crevices but has ositivelyflush surfaces at all points so that itgmaybe kept clean readilyfiandthere are no metallicrparts exposed which: would .be subject tocorrosion or, would require-fie appearance. In other words, the presentconstruction afiords a thoroughly sanitary Q and extremely durable seator cover of bakelite'material molded inone piece. 7

-' The invention ;is'-illustrated in the;acoompanying drawingswherein 1Figure 1 1s a plan view of a toilet seat constructed in accordance withthe present invention'with the hinge arms molded integral with themainbody portion of the seat. One 1 ,of; the arms appears in horizontalsection;

Throughout the 'views, similar-l'reference 5 numerals are appliedtojcorresponding parts.

metalli inserts about, through and .into

often present roughsurfaces.' Acids and alkaliescorning in contactwiththe seats unide'r service conditions attack the finish and ruin-theappearance of the seats. Furthermore, wooden seats absorb moisturereadily and often become moisture logged and, as a consequence,openatthejoints. ,ltalso fre-v quen tly happens that theseats rot at thehinges which results in the seatbecomingjexz tremely loose. There isalso:the disadvane 41 ffig 'd i .hiI gQoOnnection that these have.usually; been nickel plated and, as a result, require frequentpolishingif any semblance of I cleanliness is to be jmaintained becausethefinishis quickly attacked byal kalies and acids coming in contacttherewith.

For example, lye and other disinfectants and deodorants will "readilyattack the nickel plating; At any rate, the, plated fittings soon showevidences of corrosion and it is common experience to find heavyverdigris coatings on these parts. 1 Y

The present invention avoidstheabove enumerated objections to woodentoilet seats and covers bymolding the same of bakelite materialpreferably with the hinge arms molded integral with the main bodyportion of; the seat 01",.,cover as herein illustrated.

The chemical and physical characteristics of this material areparticularly suited for this use as zit isunafiected by acids oralkalies', does not absorb ,1110lSt11I8 and'is generally thoroughlysanitary and extremely durable.

Itnever showsevidences of Wear .and is not readily ,scratche'd, dentedor otherwise J marred. Neither will it crack or break if IOU I the hingearms because the entire seat, in'

subjected to rough usage. presents a smooth, flush surface withoutjoints even at cluding the hinge arms, is molded in one piece; itsubmits itself to easy cleaningand maintains a definite glossand lustrewithout the need -for considerable polishing. The appearance presentedisthat ofa quality product first and last and one which will'har m ze-pep ly' with t e h g estgra etois. let. fixtures. Its very sanitaryandextrerne ly l durable character causes it to make an especial appealfor use inhote-ls and other public buildings, as well as, for use inhomes.

The toilet seat, indicated by. the: reference:

numeral 5, and the toilet, seat cover 6 .are

termed of bake-l'i te material each molded in I I onepiece ipreferablywith-the hinge arms 7 and as well, 'is formed' with elongated cavities,

' shown at 8' and 8' with aview principally construction of the hingearms molded in flu tegiralwith the mainbody portions of the I seat andcover is desirable, not only from the sta-ndp'ointiof thesavingin' costwhich re-- sults therefrom, but also from, the standpointthatnocrevi'cesare formed anywhere and; ever-ythlngpresents flushsurfaceseasy I to. beakep't clean.

'As' illusir atedg thejinsert 9 is:preferably. formed from a single piece of sheet metal, the; shankportion 9 being cutaway asshown at 13, and prov'ided with: a

plurality. ofi-perforations, as indicated at 14, the: general form oftheshank portion being tubular solthat' the bakelite in molding will flow.into. .the' center aswell asabout all sides of: the shank. portion. Theout out portions- 7 1-31 and: perforations: 14-further permit the moldedmateriab to flow into these places and form aperfectibond between thebakelite anduthe; metal insert.- The head po'rtio'n 11 islooped'to:formipart.ofi aring=shaped bear ing liningwithin theopeningIQ.The. lining extendsqapprox-imately-'24sO 'within the open ing l2g=soLthatia properlbearing is a-fiorded by molded integral with the mainbody '20 portion of the seat and cover respectively. :r- Theunder-sideoftheseat, and of the'cover the desired strength'z e.

When the seat is mounted'on the toilet bowl. Obviously, the constructionis thoroughly practical and extremely durable. Due to the reinforcement,the hinge arms are practically indestructibly joined with the main 7body portion of the seat. If desired, the

hinge arms may be formed with slight cavitiesiadja'cent the juncturewith the main body portionof the seat, as'shownat 15,. which j g ves-anornamental effect withoutylessening the strength of the parts,andatthesame timeresults in a slight saving inmaterial.
